SPECIFICATION forming part of Letters P Application tiled March 29, 1881.

To all whom it may concern Beitknown that LTnoMAs MONROE BALEs, a citizen of the United States, resident at Dub- 1in, in the county of ayne and State of Indiana, have invented certain new and useful Improvements in Coekle-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 is a representation of a side elevation of my device, and Fig. 2 is a cross-section thereof.

This invention relates to improvements in cockle-machines.

Theinvention consists in the construction hereinafter set forth, and particularly pointed out in the claims.

In the annexed drawings, A is the frame of the device,B being the head, C the foot, and D the connectingboard, having the slant d at top. Secured above board D is the strip E, having an outward upward flare. Pivoted at the upper corners, f', of its ends fto the head and foot is the board F, having the downward slantvshown. This board is lined inside with metal, which is turned up on the under edge. Springs G G, pressing` against the lower coruers,]`2, ofthe ends of this board,force it in ward with a yielding pressure, which gives it aare. This forms one side of the machine. The other side, H, is a piece of metal secured to the head and foot at its ends, its bottom 7L being curved under and inward and secured to the top of board D.

I K are tworollers, round or angular, having theirjournals c' 7s working in the head and foot, one of them provided with the handle k. These rollers have the slant of the frame.

L is an endless belt, having a Width equl/ to the length of the rollers. This belt Jis co posed of strips of metal, Z, preferably tin, hinged together at their ends, said strips having secured to their upper surfaces similarshaped strips, M, preferably of zinc, provided with perforations m, too small and shallow to atent No. 250,870, dated December 13, 1881.

bottom of the recesses made by such perforations.

The rollers I and K are not situated in a vertical plane but the lower one is somewhat out of the vertical plane of the other toward the board D, so that when the beltiug is on the surface of the latter will come in sharp contact with the lower edge of said board, and 'the slant ofthe two forms a trough, at the upper end of which is located the hopper N and at the lower the spout P. This belting L is located with relation to the metal side H so as to be ott' from its vertical portion, leaving a passage, h2, and from its curved bottom,forming therein a trough, which has opening h3 at the bottom of its lower end, inside the foot C.

r[.he grain-wheat or other grainmixed with cockle is poured into hopper N and the belt L is turned by the handle lc. As the sections spring-pressure ou the side board, F, allows for the deviations in said sections caused by the hinge movement. The stuff poured in runs down the inclined trough formed between board F and belt L, and the recesses in the sections of the latter catch the cockle and separate it from the grain, carrying it over and dropping it in trough 71,2 below, from which it slides through openings h3 to the ground beneath. The recesses not being large enough to hold the grain, and their bottoms being made of metal too smooth to hold the grain by friction, particularly wheat, which is quite fuzzy, it runs down and out of spout P into a receptacle placed-below. The width given to the sections and the slant to the belt present a straight and almost vertical wall to the wheat, which keeps any drag from carrying the grain up.

I claim- 1. In a cockle-machine, the combination, with the inclined frame A, of the inclined angular /otatiug shafts I K, the lower one being placed to cause the endless belt to incline upwardly and outwardly, as shown, the endless belt L, consisting of hinged plates extending lengthwise of the rotating shafts and having their surfaces covered by perforated plates of a size corresponding thereto, and the metallined pivoted side F, inclined toward the belt, and
